/**
*
* Класс для отправки почты. Для работы должна быть разрешена функция mail.
*
* Примеры:
*
* // письмо с аттачем
* $mail = new Mail;
* $mail->charset("windows-1251"); // по умолчанию utf-8
* $mail->to("recipient@example.com", "Имя получателя"); // имя можно опустить
* $mail->subject("Заголовок");
* $mail->body("Сообщение");
* $filename = "path/to/file.rar";
* $mail->attach(file_get_contents($filename), basename($filename), "application/x-rar-compressed");
* $mail->attach("пусто", "Текстовый документ.txt", "text/plain"); // с распознанием русских символов в имени приложения проблем не возникнет
* $mail->send();
*
* // несколько адресатов
* $mail = new Mail;
* $mail->to(array("recipient1@example.com" => "Имя первого получателя", "recipient2@example.com" => "Имя второго получателя"));
* $mail->subject("Заголовок");
* $mail->body("Сообщение");
* $mail->send();
*
* // рассылаем копии письма
* $mail = new Mail;
* $mail->subject("Заголовок");
* $mail->body("Сообщение");
* $emails = array("recipient1@example.com", "recipient2@example.com");
* foreach ($emails as $email) {
* $copy = copy $mail;
* $copy->to($email, "Лично");
* $copy->send();
* }
*
* Поля From, Reply-To, Cc и Bcc можно задать с помощью одноименных методов
* (в случае с Reply-To - reply) аналогичных по синтаксису методу to, существует
* возможность добавления произвольного заголовков с помощью метода add.
